Per local/AGENTS.md Rule 2 (NO OVERLAY-STYLE PATCHES — AMENDED 2026), big
external projects must NOT have source forks in local/sources/. libdrm's
Red Bear edits now live as external patches in local/patches/libdrm/,
matching the established pipewire and wireplumber migration pattern
(commits 8ff9da2ff, 722f0c452).
The 5 patches were recovered from git history (commit 89d1306c8^ —
the migration that deleted them) and renamed to the modern Rule 2
NN-prefix naming for lexical-order application:
01-drm-ioctl-bridge.patch (P1 from old series, 278 lines)
02-ioctl-response-sizes.patch (P1 from old series, 30 lines)
03-drm-get-pci-info.patch (P2 from old series, 153 lines)
04-drm-get-version-driver-name.patch (P3 from old series, 34 lines)
05-drmGetDeviceFromDevId-redox.patch (P4 from old series, 68 lines)
These patches add the Redox-side ioctl/ioctl-com and scheme: dispatch
path needed by redox-drm and Mesa radeonsi/iris.
The recipe now points at upstream libdrm 2.4.125
(https://gitlab.freedesktop.org/mesa/libdrm, tag libdrm-2.4.125) and
applies the patches via a [source].script hook (the cookbook's
"Optional script to run to prepare the source" field) with a
REDBEAR_PATCHES_DIR computed from COOKBOOK_RECIPE.
Fixes the broken state where the recipe referenced the now-deleted
local/sources/libdrm/ fork.
